ESPN's Josina Anderson spent some time recently with Minnesota Vikings tailback Adrian Peterson in Houston, where Peterson is conducting part of his rehabilitation from knee surgery. This clip offers some higher-quality footage of his work than I was able to provide via Twitter a few weeks ago.

Asked how likely it is that he will be on the field for the Vikings' Week 1 game against the Jacksonville Jaguars, Peterson said: "Ultimately I'm going to be smart and do what's best for me. I know my body. I know if once that Week 1 comes, regular season, if I'm going to be able to go out and perform the way I know I need to. And I know I'm going to be able to do that."

Earlier: Peterson's career arc isn't lining up with the timing of the Vikings' latest rebuilding project.
